What racers and reviewers say
- RaceRaves (59 ratings, 15 marathon)Raced 2025 · aggregator · mostly positive
4.4 of 5 from 59 ratings. Runners agree on ocean views, strong organization, and good swag. They disagree on hills: some say gentle, others relentless on the second loop. The doubled loops and highway stretches are the main criticisms; the 6 hour cutoff drew one complaint.
“Hills tough but manageable, with ocean views most of the way”
- Marathon Maniacs member reviewsRaced 2024 · aggregator · very positive
Nine reviews scoring 9 or 10 of 10 from 2018 to 2024. They praise ocean views, an uncrowded course, perfect weather and tidy organization. A double out-and-back on Highway 101 with many rolling seaside hills makes even pacing hard; post-race food was weak in 2023.
“The course is never crowded”
- FindMyMarathon race reviewsRaced 2026 · aggregator · very positive
Five 5 star reviews. Mile 2 is the steepest climb and the lagoon climbs bite late; hold pace until the mile 18 turnaround. Aid stations well spaced, mall lot parking still available 45 minutes before the start, and weather described as perfect.
“Incredibly scenic, well organized”
- MarathonGuide race reviewsRaced 2024 · aggregator · Positive
Two reviews. A 2024 first-time marathoner found it prettier and less hilly than feared, but disliked doubling back and felt the 4:00 pacer ran ahead. A 2022 runner loved Highway 101 ocean views and January weather but warned the hills are hard for runners used to flat courses.
“Ocean views along Highway 101 and mild January weather”
- Amusings (personal blog), 2016 race recapRaced 2016 · blog · neutral
A January 2016 recap of a 3:35 finish. The runner faded after mile 18 (29 km) and cramped near the finish, helped by a friend.

Short reviews: water at every mile and electrolyte nearly as often, easy parking and expo in a mall lot, a mostly flat out-and-back with a few rollers, and a course that rises only about 75 ft (23 m) above sea level.
“Water every single mile”
- Sunrise Running Company event pageRaced 2025 · article · neutral
